22 | * @class AliHLTTPCClusterFinderComponent | |
23 | * Implementation of the cluster finder component. | |
24 | * The component implements the interface methods of the @ref AliHLTProcessor. | |
25 | * The actual cluster finding algorithm is implemented in @ref AliHLTTPCClusterFinder. | |
6b15c309 | 26 | * Two components are registered, TPCClusterFinderPacked and TPCClusterFinderDecoder. |
27 | * TPCClusterFinderDecoder use the AliTPCRawStream class for decoding of the data, while TPCClusterFinderDecoder | |
28 | * use the AliAltroDecoder for decoding the data. | |
29 | * | |
30 | * TPCClusterFinderDecoder is the fastest of the two, this is due to that the AliAltroDecoder | |
31 | * returns data in a bunch format. A bunch consist of consecutive signals. | |
32 | * TPCClusterFinderPacked first have to read the data one by one, which means that row, pad and | |
33 | * time signals have to be compared between each new digit, which leads to a slower alorithm. | |
84645eb0 | 34 | * |
d9e5f6f3 | 35 | * |
36 | * The clusterfinder is now using the AliTPCTransform instead of the AliHLTTPCTransform for | |
37 | * transformations from row, pad time -> x,y,z. | |
38 | * | |
